<h2 id="sec_attention">注意</h2>
<p>Only the contour points are transformed. As the polar transformation
is not affine, <code><span data-if="hdevelop" style="display:inline">polar_trans_contour_xld</span><span data-if="c" style="display:none">polar_trans_contour_xld</span><span data-if="cpp" style="display:none">PolarTransContourXld</span><span data-if="com" style="display:none">PolarTransContourXld</span><span data-if="dotnet" style="display:none">PolarTransContourXld</span><span data-if="python" style="display:none">polar_trans_contour_xld</span></code> only produces
reliable results if the spacing of the contour points is
small. Existing attributes are not transformed.</p>
